WCCO was an AM station, so, single-mike mono. I recall a pretty nice fight when I asked Master Control to disable the CBS (tube-type) Audimax during the concert. WCCO's 50 kilowatt big stick allowed for a good deal of quieting so we got away with it <g>.

So you set up 1-mic mono pickup, or 3-mic stereo? Also, you are spot-on about Collins. I found a photo of the one Mercury recording session in Louisville in 1950. That mixer and those early Ampex 300 machines were used there, too. And there's a front view of the mixer, showing the Collins insignia. I think that mixer was used in the first iteration of the recording van, feeding the two Fairchild machines. The Fairchilds, by the way, theoretically would print less audible scrape-flutter because the tape path was a loop around the heads with rolling guides on each side of the loop (thus less length of "string" to vibrate between the roller and heads). -- Tom Fine ----- Original Message ----- From: "Mark Durenberger" <[log in to unmask]> To: <[log in to unmask]> Sent: Monday, September 28, 2015 3:53 PM Subject: Re: [ARSCLIST] a piece of Minneapolis Symphony and Mercury Records history > ...And now that I blow up that photo it seems those are the original fader > knobs; sorry... > > > Regards, > > Mark Durenberger > > -----Original Message----- > From: Mark Durenberger > Sent: Monday, September 28, 2015 2:50 PM > To: Association for Recorded Sound Discussion List > Subject: Re: [ARSCLIST] a piece of Minneapolis Symphony and Mercury > Records history > > Mixer is almost certainly a Collins.
